You might want to look at the source for the R 'its' package. It defines
an S4 class for an irregular time series whose representation
consists of
1. a matrix portion analogous to your vector portion to hold the series
of multivariate series, and
2. a "dates" slot analogous to your accurate s
Hi Martin

"accuracy" slot. Which leaves me puzzled as to why anyone would define
a vector class such as "string" (p315). I can't see why "string" is
defined as
